Licensed air conditioning and HVAC services across the Central Coast and Lake Macquarie — built on honest advice, tidy workmanship, and quotes you can trust.
I'm the owner and principal technician at Lilac Air Conditioning. With years of hands-on experience serving homes and businesses across the Central Coast and Lake Macquarie, I built this company on a simple foundation: clear quotes, honest advice, and tidy workmanship.
When your air conditioning breaks down, you need someone you can trust to fix it quickly and correctly — not a call centre, not a subcontractor you've never met. When you call Lilac, you get me. I personally oversee every installation, repair, and maintenance job we take on.
Based in Cooranbong, I'm genuinely local. I know the Central Coast's climate, the types of homes in each suburb, and the HVAC systems that perform best in our conditions. That local knowledge makes a real difference to the quality and longevity of every job I do.
Fully qualified and insured for your complete peace of mind. All work meets NSW regulatory requirements.
Expert installation and servicing of Hitachi and Temperzone systems — two of the most reliable brands available.
Transparent pricing with no hidden extras. The price we quote is the price you pay — guaranteed.

"Not expecting our air conditioning to stop on one of the hottest days of the year, I contacted Gary and he advised me straight away his availability and turned up to review our situation. Unable to source spare parts for our older unit, Gary was up front and honest in quoting, supply and installation. I would highly recommend Gary for his experience, knowledge and thorough communication. Thanks Gary"
